OASTERAN J. MARIUS, OF WEST HOBOKEN, NEW JERSEY, ASSIGNOR TO STEPHEN J. COX, OF NEW YORK, N. Y.

ELECTRIC ROLLER.

SPECIFICATION forming part of Letters Patent No. 715,677, dated December 9, 1902.

Application filed February 6,1900. Serial No. 4,258. (No model.)

To aZZ whom, it may concern:

Be it known that I, OASTERAN J. MARIUS, a citizen of the United States, residing at WVest Hoboken, Hudson county, and State of New Jersey, have invented certain new and useful Improvements in Electric Rollers, of which the following is a specification, sufficient to enable others skilled in the art to which the invention appertains to make and use the same.

Myinvention relates to means for applying electricity to the body superficially; and it consists, primarily, in utilizing the motion of a contact-roller for the purpose of operating a generator by which electricity is supplied to electrodes adapted for direct application to the body, and, secondarily, in certain special features in the construction and arrangement of parts hereinafter set forth.

In the accompanying drawings, Figure 1 is an elevation of my improved electrical roller; Figs. 2 and 3, elevations of opposite ends thereof. Fig. 4 is a sectional elevation of the roller. Fig. 5 is an elevation of the magneto and gear frame. Fig. 6 is a similar view, taken at right angles to Fig. 5. Fig. 7 is a transverse section taken upon plane of line 7 7, Fig. 5; Fig. 8, a transverse section upon plane of line 8 8, Fig. 5; Fig. 9, a transverse section upon plane of line 9 9, Fig. 5; Fig. 10, a transverse section upon plane of line 10 10, Fig. 5; Fig. 11, a View of the inner side of the switch-plate; Fig.12, a section upon plane of line 12 12, Fig. 11, the spindle being shown in elevation; Fig. 13, a section upon plane of line 13 13, Fig. 5; Fig. 14, a viewshowing one of the elastic contacts; Fig. 15, a sectional elevation upon plane of line 15 15, Fig. 4; Fig. 16, an elevation of a portion of the driving-rack; Fig. 17, a section of the driving-rack and adjoining portions of the shell. Figs. 7 to 17, inclusive, are upon an enlarged scale. Fig. 18 is a sectional elevation through the magneto gear-frame, &c. Fig. 19 is a diagrammatic view showing the electric circuit.

The hollow roller R consists of a cylindrical shell S, of insulating material, upon which fit electrodes N and P, a central collar or shoulder 8 being preferably provided upon the shell S, against which the opposed ends of the electrodes abut.

M represents a permanent magnet, and A an armature rotatable between the poles thereof. Attached to the poles of the magnet is suitable framework F for the support of the gearing, &c., hereinafter described. Projecting from this framework is a stud f, supported by onearm h of the handle H, another stud m projecting from the magnet M and being supported by the other arm h of the handle. The magnet M and frame F are held rigidly between the arms h h of the handle H by any suitable means, as by forming one of the studs m with a tenon m, which is angular in cross-section, and constructingits socket in the arm h to correspond or by any other mechanical expedien t,the essential feature in this construction being that the magnet M and framework F shall be practically integral with the handle, having no movement thereon.

Each studfm is formed with a cylindrical portion or journalf m supporting the roller R in such manner that itis free to rotate upon its longitudinal axis. Thus the outer ends of the electrodes P and N are respectively secured to disks of insulating material D D, which bear upon the journals f m and constitute the hubs of the roller.

d d are metallic bearing-plates secured to the hub-disks D D, and d d are washers interposed between the parts to prevent play or looseness and are merely incidental to the construction shown.

C is an elastic plate mounted upon the end of the magnet M and in electrical contact therewith and with the electrode P, and O is a similar electrical contact-plate situated on the outer plate f of the frame F and insulated therefrom by a plate E, of insulating material, but in electrical contact with the electrode N and with the brush B,which bears against the commutator K of the armature A.

The armature-shaft a is supported by and between the disk f forming the base of the frame F, and the cross-bar m within the arms of the magnet M. One end of the armaturecoil ends in the armature itself, while the other ends in the commutator K. The outer end of the armature-shaft is provided with a pinion a, which meshes into the gear-wheel 9 upon the counter-shaft g, also carrying a pinion g which in turn meshes with the gear t upon the shaft t". This latter shaft 7 also carries a pinion 1' which meshes with the driving-gearj on shaft j, said driving-wheel engaging directly with the annular rack s, secured to the interior of the shell S. Thus it will be seen that (the magnet M and frame F being held rigidly by the handle I-I) any motion of the roller will be transmitted by the rack 8 through theintermediate gearing to the armature-shaft, rotating the armature and creating electric energy.

It is obvious that the intermediate gearing employed may be varied to afford any relative speed desired, and I do not confine myself to the particular form and arrangement of parts shown in this respect. In the construction illustrated in the drawings the armature is designed to make about thirty-live revolutions to one of the roller R.

()n the shaft g is a breaker-wheel or vibrator V, the teeth or projections in which come successively in contact with a metallic tongue L when the latter is brought into proper position. This tongue L is mounted upon a rocker-arm Z, pivotally connected to the disk f of the frame at Z. The rockerarm Z has a stud Z which engages with aslot q in the switch-arm Q. This switch-arm Q is secured to the inner end of a spindle Q, which passes through the hollow stud f and has attached to its outer end the switch lever or handle g, by which the metal tongue L may be thrown into or out of engagement with the breaker or vibrator V. The brush B is electrically connected with the contact-plate O by an insulated wire, and the said disk is in like manner connected electrically with the metallic tongue L.

In Fig. 19 the essential parts are represented diagramatically, intermediate gearing, &c., being omitted. Thus, by way of illustration, supposing the metal tongue L to be thrown out of position for contact with the teeth of the vibrator V, the current generated by the rotation of the armatureA may be said to pass out from one end of the wire through the commutator K, brush B, contact-disk C, and electrode N to the body and thence to the electrode P, which returns it by way of the contact-disk C, magnet M, cross-bar m shaft to, and armature to the other end of the wire, thus completing the circuit. When the metallic tongue L is thrown into position for contact with the teeth of the vibrator V, the result is that whenever said tongue Lis in contact with a tooth of said wheel V the current flows from the contact-plate 0 through said tongue L, vibrator V, and gearing to shaft a and thence again to the coil, thereby charging said coil and then discharging the same over the normal circuit first described when contact between the tongue L and vibratortooth V is broken. Thus an intermittent current may be produced consisting of a series of intensified shocks when desired.

I have herein shown and described a magneto-electric generator, although it is obvious that any mechanical generator of electricity may be substituted with like result and without departing from the spirit and intent of my invention, the distinguishing feature of which is the utilization of the rotation of the contact-roller for the purpose of generating an electric current by mechanical means in a broad sense without limitation to any specific form of generator and in contradistinction to the employment of electrochemical batteries for a like purpose. In fact, the device supplies its own electricity and is not dependent upon galvanic action or external sources of supply in applying the electric current to the human body. The application of a mechanically-produced electric current to the human body in lieu of the galvanic current is also considered more beneficial and effective by medical authorities.

By my invention I attain a permanent portable electrical generating device in no wise dependent upon batteries and adapted for use under all conditions and climates, practical and commercial advantages which establish the value and importance of my improvement in the art. The device is automatic in that the act of using it upon the body generates the electrical current.

What I claim as my invention, and desire to secure by Letters Patent, is
